The map information management system 3 may be an electronic device. The map information management system 3 includes a geographic information storage unit 32, a geographic information processing unit 31, a traffic map generation unit 33, and a GIS server 4. The geographic information processing unit 31 may connect to the GIS server 4 inside the map information management system 3. The GIS server 4 may provide map information to the user for relevant map applications, such as map browsing, location and path planning, etc. The map information processing unit can download the GPS geographic data from the server and store the GPS geographic data in the geographic information storage unit 32 according to the information of the specific location and/or the route. The traffic map generating unit 33 generates a corresponding traffic map according to the GPS geographic data.
The service information management system 2 may be an electronic device. The service information management system 2 includes a service storage unit 21 and a service processing unit 22.
As shown in fig. 2, the service processing unit 22 acquires road management data of a specific place from the terminal device 1 by communication transmission. The service processing unit 22 acquires GPS geographical data from the geographical information storage unit 32 through data transmission. In the service processing unit 22, the location information of the GPS geographical data is extracted and compared with the location information of the second field of the road management data. And if the location information of the GPS geographic data is consistent with the location information of the road management data, extracting specific location data in the GPS geographic data. And packaging the GPS geographic data into the road management data to generate road management map data.

It should be noted that the map scale can be adjusted according to the resolution of the display unit (not shown) of the electronic device or the additional device, so that the initial map can include all the specific locations when displayed in the display unit. And then, the initial map is used as a center to extend outwards to form an extension map, and the GIS server 4 downloads and stores the extension map.
It should be noted that the purpose of extending the initial map outward into an extended map centered on the initial map is to increase the range of map information that can be retrieved. Meanwhile, the range of the resolution of the corresponding display unit may be extended outward with the initial map as a center, respectively, to become an extended map. It should be noted that the extension degree of the initial map can be designed and adjusted according to different requirements, and is not limited thereto. The initial map may be directly downloaded and stored by the GIS server 4 without adjustment. The map stored in the geographic information storage unit 32 can provide a map information search of a corresponding specific location without the service processing unit 22 connecting to the GIS server 4.
Example 2: a system for generating a traffic map for a traffic order management platform, which is different from embodiment 1 in that, in this embodiment, specific locations can be grouped, and each group can download location data separately.
Information of a plurality of specific locations is acquired. Similarly, the location-specific information may be obtained from the GIS server 4 via a network or directly from within the service processing unit 22. The specific sites are grouped to obtain a plurality of groups. Each group of which may include at least one specific location. It is noted that, in some embodiments, the distance between each specific location in each group is smaller than the predetermined value. In other words, different specific locations will be divided into the same group when they approach each other.
As shown in fig. 3, the specific locations LM1, LM2, LM3, LM4, and LM5 are close to each other, and the specific locations LM6, LM7, and LM8 are close to each other. Therefore, the specific sites LM1, LM2, LM3, LM4, and LM5 are divided into the same group, and the specific sites LM6, LM7, and LM8 are divided into the same group. Then, for each group, the map scale is adjusted so that the initial map can include all of the specific locations in the group. Similarly, in some embodiments, the map scale may be adjusted according to the resolution of the display unit of the service processing unit 22 or the additional device, so that the initial map may include all the specific locations in the group when displayed in the display unit. And then, the initial map is used as a center to extend outwards to form an extension map, and the extension map is downloaded and stored by the GIS server 4 through the network. Similarly, in some embodiments, the range of resolutions of the respective display units may be extended outward, respectively, centered on the initial map to become an extended map. In some embodiments, the initial map may be downloaded and stored directly by the GIS server 4 without adjustment. Then, it is determined whether all groups have been processed. If not all groups have been processed, the groups that have not been processed are selected and the operation is repeated. If all groups have been processed, the process is ended. Similarly, the map stored in the geographic information storage unit 32 can provide location data retrieval of a corresponding specific location without the service processing unit 22 connecting to the GIS server 4.
Example 3: a system for generating a traffic map for a traffic order management platform, which is different from embodiment 1 in that, in this embodiment, each specific location can individually perform a map information download operation.
Information of a plurality of specific locations is acquired. Similarly, the location-specific information may be obtained from the GIS server 4 via a network or directly from within the service processing unit 22. Then, for each specific location, the map scale is adjusted so that the initial map is centered on the specific location and includes streets around the specific location. In other words, this initial map is the map information of the street level. And then, the initial map is used as a center to extend outwards to form an extension map, and the extension map is downloaded and stored by the GIS server 4 through the network. Similarly, in some embodiments, the range of resolutions of the respective display units may be extended outward, respectively, centered on the initial map to become an extended map. In some embodiments, the initial map may be downloaded and stored directly by the GIS server 4 without adjustment. And then judging whether all the location data has been processed. If not, selecting the location data which has not been processed, and repeating the operation. If all the location data have been processed, the process is ended. Similarly, the map stored in the geographic information storage unit 32 can provide a map information retrieval of a corresponding specific location without the service processing unit 22 connecting to the GIS server 4.
Example 4: a system for traffic map generation for a traffic order management platform is different from embodiment 1 in that, as shown in fig. 4, a GIS server 4 is located outside a geographic information management system. The geographic information processing unit 31 of the geographic information management system is connected in communication with the GIS server 4.
The above description is intended to be illustrative of the present invention and is not intended to limit the scope of the invention, which is defined by the appended claims.
